LETHOD F FORMING VARIOUS UNITS FROM STANDARDIZED BLANKS Arthur L. Parker, Cleveland, Ohio Application April 25, 1938, Serial No. 204,198

. 3 Claims.

The invention relates generally to the art of metal working and primarily seeks to provide a novel forged, cast or otherwise formed cast metalblank standardized so that a. variety of units can be formed thererfom, and a novel method of utilizing the blank in the formation of such units.

In the formation of tube or pipe couplings,

valves and the like, it is the common practice to individually design and form the forging or casting to be worked up into each particular unit.

This practice necessitates the use of individual hammer and anvil structures, in the case of forging, die structures in the case of die casting, and

molds in other types of casting, for each unit to 5 be made, and obviously the expense and labor necessarily expended in providing and handling this equipment is undesirably'great.

An object of the invention is to provide a novel method of forming units comprising the formation of a standard blank embracing all design features of a variety of units to be made up, and the working of the standard blank to form the particular design of unit desired.

In the dratving- Fig. 1 is a face view of a T-shaped standard blank constructed in accordance with the invention;

3 vidual design;

Fig. 3 is a view similar to Fig. 2 illustrating the working of the blank to form a unit of another design.

I provide a standardized unit generally designated 5, which in this particular illustration, is T.-shaped and may be formed by any of the well known methods of drop forging, die casting, or in any other suitable manner.

40 Thestandard blank unit is formed to embrace the design features of a variety of individual tube 55 standard blank removed initially in the forma- Fig. 2 is a view similar to Fig. 1 showing the blank of Fig. I worked to provide a unit of indi- In thepractical development of the inventiontuberance l0 extending axially of the particular tion of said unit. The formed unit includes an externally threaded male extension II at one end of the T, an internally threaded counterbore I2 at the opposite end ofthe T and communicating with a male seat l3 for effecting a flared 5 end tube coupling, and another internally threaded counterbore H in the remaining leg of the T. In the formation of this unit the head ,of the T is initially bored as at I5, prior to the formation of the threaded counterbore l2, and the 10 other leg of the T is bored as at 16 prior to the formation of the threaded counterbore M.

In Fig. 3 of the drawing, I have illustrated the formation of another individual design of unit and in this illustration also the completed unit 15 is illustrated in full lines and the excess metal portions of the standard blank removed in the formation of the unit in dot and dash lines. In the formation of this unit the T-head is initially bored as at H, the other leg of the T is bored as 20 at IS, the metal of the vertical leg is reduced and the remaining portion of the leg worked to provide an externally threaded male extension [9, and each end of the T-head is worked to provide an externally threaded male extension 20 of individual design, including a coniform male seating portion 2|.

From the foregoing description it is thought that the details of construction and advantages of my improved blank will be readily understood by those skilled in the art to which it relates, as

well as my improved method which includes the formation of a standardized blank embracing all up, and the working of the standard blank to form the particular design of unit desired.

What I claim is:

1. A method of forming tube-coupling units comprising the formation of a standard blank 40 with a plurality of legs, each leg including a noncircular head and a protuberance extending ax-- ially of the leg beyond the head, removing certain of the heads and protuberances, or portions thereof, to form ablank ofparticular design, and working the remaining portions of the legs to form from said standard blank a tube coupling of selected design.

2. A method of forming tube coupling units comprising the formation of a standard blank .50 with a plurality of legs, each leg including a noncircular head and a protuberance extending axially of the leg beyond the head, removing the protuberances from any leg or legs, and intercomprising the formation of a standard blank with a plurality of individual bosses, each boss including a non-circular head and a protuberance 10 extended axially ot the boss beyond the head,

removing the protuberances from 'any selected boss or bosses, and internally working the head on such boss or bosses to receive a tube or pipe, removing 'the non-circular head from the remaining boss or bosses and externally working such remaining boss or bosses to provide a male piece for a tube or pipe connection to form from said standard blank a tube coupling unit of selected design.
